Title:
AUTOMATIC VIBRATION METHOD AND APPARATUS FOR HYDRAULIC EXCAVATOR
Document Type and Number:
WIPO Patent Application WO/1991/010783
Kind Code:
A1
Abstract:
This invention relates to an automatic vibration method and apparatus for a hydraulic excavator which is used for a hydraulic excavator having a work machine consisting of booms, arms and bucket and applies suitable vibration to the work machine in order to reduce excavation resistance despite the change of nature of the soil and diversified tasks and to conduct efficiently the excavation work. Particularly in the present invention, an operation mode (Bo, A, Bu, Sk) and vibration mode (L, M, S) are set in advance in accordance with nature of the soil and an operation pattern, and suitable vibration is automatically generated as an automatic vibration mode. The operation load of a work machine lever is included with the vibration described above. For this reason, even in a simple and delicate repetition work such as the rolling work, the sieving work or the excavation work with vibration applied to the bucket, the work can be executed easily and uniformly without imparting a great deal of load and fatigue to the operator, and work efficiency can be improved drastically.
